Oct 1, 2025

October 2025 (portiaAI/docs): Delivered a centralized, on-demand documentation testing workflow by introducing a manual trigger via workflow_dispatch. This replaces the prior daily cron with explicit control over when docs tests run, improving test relevance and reducing unnecessary CI usage. Change implemented through CI configuration updates; commit d2fb98a0f02d9db98104b5f96cd7107949e86433 (Update docs_cron.yml (#392)). Major bugs fixed: None reported this month. Overall impact: faster feedback loops for documentation changes, reduced CI resource usage, and improved test reproducibility and visibility. Technologies/skills demonstrated: GitHub Actions workflow_dispatch, YAML-based CI configuration, CI/CD automation, and cross-team collaboration with docs/QA teams.
